Conventionally, in this type of vending machine, for example, as shown in Japanese Patent Application Laid-Open No. 61-211795, a product storage column loaded with a plurality of products such as ice cream is placed in the storage compartment, and used for injecting money. At the time of the sale of the accompanying product, the product is discharged from the product storage column, and the product is discharged from the discharge port to the product sales port.

Usually, the commodity storage column incorporates spirals as shown, for example, in Japanese Patent Application Laid-Open No. 61-126378 and Japanese Patent Application Laid-open No. Hei 1-72682, and in the spiral at predetermined intervals up and down. The product is loaded and the product is dropped and discharged from the lower spiral terminal by rotating the spiral, for example, by 180 degrees during one sale.

According to such a conventional structure, for example, when a product is loaded in a sparrel of a product storage column, the intermediate is loaded, that is, in the above-described conventional example, the distance between the product and the product is opened by 180 ° or more at the rotation angle of the spiral. In this case, there is a problem that the next product does not fall even if the spiral rotates, and the product is not sold even though money is injected.

It is an object of the present invention to provide a vending machine which detects a delivery situation of goods from an outlet, resumes goods discharge operation, and prevents a state in which such goods are not sold.

It is still another object of the present invention to provide an automatic vending machine that prevents fraudulent duplication such as duplication caused by bad mischief in the detection means when the delivery situation of the goods is detected and the discharge operation of the goods is resumed. It aims to provide.

At the same time, the product sales port 5 which opens the front as a hole 4 which takes out a product is provided in the lower part, respectively.

The opening and closing of the product taking-out hole 4 is freely opened and closed by the sales phrase 6 in which the upper terminal is freely axially supported and rotated toward the inner product sale opening 5 to open the opening 4 for taking out the product. .

At the upper part of the merchandise sales section 5, a sales switch 28 is provided at the rear of the sales phrase 6, which is normally open as a sales phrase open / close detection means of the present invention. When rotated in the direction of the product sales opening 5, it contacts with this sales opening switch 28, and is comprised so that a contact may be closed. The main body 1 is formed by a heat insulator 7, a storage compartment 9 having an opening 8 opened on the front surface thereof, and a machine room 10 installed below the storage compartment 9. Have

In this machine room 10, the compressor 12, the condenser 13, etc. which comprise the refrigerating circuit to the cooler 11 installed in the lower part of the storage 9 are arrange | positioned.

In the storage 9, a door 14 for merchandise storage is provided on the front surface so as to be openable and closed, and a product storage column 16 having spirals 15 provided up and down is provided in plural in parallel.

Goods G, such as ice cream, are loaded into the spiral 15 at predetermined intervals (not shown in FIG. 1).

In addition, a sales electric motor 27 for rotating the spiral 15 is installed at the upper end of each of the commodity storage columns 16, and again discharged by the spiral 15 under the commodity storage column 16. The product activator 17 which guides and delivers the falling product G to the goods sales opening 5 of the outer door 2 is provided.

The front opening 8 of the storage 9 is divided up and down, and the opening and closing is made possible by the heat insulation doors 18 and 19 provided so that rotation of each end may be freely axially supported.

The upper insulated door 18 contacts the back surface of the lower end with the support member 20 so that the opening 8 corresponding to the front of the product storage column 16 can be closed, and the product is opened when the door is opened. The door 14 of the storage column 16 can be opened and closed.

On the other hand, the lower heat insulating door 19 abuts the back surface of the upper end with the support member 20 to enable closing of the opening 8 corresponding to the front of the product lifter 17 and at the same time opening the door. Therefore, the inspection and repair of the cooler 11 located behind the goods lifter 17 or the goods lifter 17 can be performed.

In this way, the upper and lower heat insulating doors 18 and 19 are provided to be opened and closed independently of each other.

The outlet 22 for opening the goods G guide | informed to the goods lifter 17 to the goods sales opening 5 is formed in the lower insulation door 19 at the open side.

Outside the outlet 22, there is provided an outlet door 23 through which the door is opened at the time of selling the product in which the goods G are discharged from the goods storage column 16.

The discharge door 23 is supported by the arm 24 so as to be movable, and at the same time, when it is moved upward, the discharge port 22 is opened, and when moved downward, the packing 26 installed around the inner surface is discharged ( 22) It is configured to close the discharge port 22 in compression contact from the front around the front surface, and is opened and closed at the time of sale by the drive motor 25.

Further, between the heat insulating door 19 and the discharge door 23, a hanging plate 30 as the product delivery detecting means of the present invention is provided corresponding to the discharge port 22. As shown in FIG.

The hanging plate 30 is composed of, for example, a lightweight polycarbonate plate of about 0.3 mm, and a hinge 31 made of nonmagnetic material such as stainless steel is attached to the upper end as shown in the enlarged perspective view of FIG. .

The hinge 31 is fixed to the front surface of the insulated door 19 above the outlet 22, and the lower hinge plate 31B extends to the outlet 22 so that the hanging plate 30 is the outlet 22. In the part, the swing is freely supported.

The hanging plate 30 has a dimension which substantially closes the outlet 22 in the stretched state, and is rotatable in the direction of the merchandise sales port 5 as indicated by the fourth center line from the state.

The rotational connection portion 31A of the hinge 31 is attached to be located outside the packing 26 at the time of closing the discharge door 23, thereby blocking the cool air from the storage 9 and rotating the connection portion. Freezing of (31A) is prevented.

Moreover, the hinge plate 31B extends toward the side surface, and the magnet 32 is attached to this extension part.

A bend end switch 33 made of a lead switch is attached to the front surface of the heat insulating door 19 corresponding to the magnet 32. When the hanging plate 30 is in a stretched state, the magnet 32 is The magnet 32 moves from the bend end switch 33 as the hinge plate 31B moves toward the merchandise outlet 5 with the operation of the hanging plate 30 proximate to the bend end switch 33. Associated with separation, the bend end switch 33 is configured to open a contact when the magnet 32 is close, and close the contact when spaced apart.

In addition, as described above, the hinge 31 is made of a nonmagnetic material to prevent malfunction of the bend end switch 33.

Next, the selling operation of the vending machine V will be described with reference to the circulation diagram of the control circuit 35 as the control means shown in FIG.

The control circuit 35 is constituted by a general-purpose microcomputer, and the terminal voltage of the bend end switch 33 connected to the power supply via a resistor is input to the input terminal 35A via the inverter 36.

In addition, the terminal voltage of the outlet switch 28 connected to the power supply via a resistor is input to the input terminal 35B of the control circuit 35 via the inverter 37.

In addition, an inverter 38 is connected to the output terminal 35C of the control circuit 35, and a sales motor 27 is connected between the output of the inverter 38 and the power supply.

In addition, the inverter 40 is connected to the output terminal 35E of the control circuit 35, and the drive motor 35 is connected between the output of the inverter 40 and the power supply.

Note that the sales motor 27 is actually present for each of the plurality of product sales columns 16, but only those of the product storage column 16 for the products selected by the product selection button are shown here.

Incidentally, the degree of circulation is shown only for the control of the sales motor 27.

When the product selection button is pressed after the coin is put, the selling command signal M of the corresponding product is input to the input terminal 35D of the control circuit 35.

When the selling command signal M is input, the control circuit 35 first sets the output terminal 35E to a high potential (hereinafter referred to as "H").

As a result, the output of the inverter 40 becomes low potential (hereinafter referred to as "L"), and the drive motor 25 is energized to move the discharge gate 23 upward as shown in FIG. The control circuit 35 returns the output terminal 35E to " L " to stop the drive motor 25 and maintains the state.

At this time, since the hanging plate 30 substantially closes the discharge port 22, even if the discharge door 23 is raised, leakage of cold air from the storage 9 hardly occurs.

Next, in step S1 of FIG. 6, the output terminal 35C is set to "H", the output of the inverter 38 is set to "L", and is energized and rotated by the sales motor 27, and the spiral 15 Rotate).

Next, the bend end switch 33 is closed in step S2, and it is detected whether the output of the inverter 36 has become " H "

Next, in step S3, it is determined whether the spiral 15 has been rotated by 180 degrees, and the sale is finished. If NO, the process returns to step S1.

When the spiral 15 is rotated 180 ° and the sale is finished, the product discharge operation is finished, and the flow proceeds from step S3 to step S4 to determine whether the bend end switch 33 is closed.

Here, when the goods G are discharged from the goods storage column 16 as indicated by the dotted line in FIG. 7 by the rotation of the spiral 15, the goods G are guided to the goods lift 17. The hanging plate 30 reaching the discharge port 22 is pushed back toward the merchandise sales port 5 to freely swing, and falls into the merchandise sales port 5.

When the suspended plate 30 is operated by the passage of the product G, the contact is closed because the magnet 32 is separated from the bend end switch 33.

Therefore, the process proceeds from step S4 to step S8, the flag is reset to end the selling operation, the control circuit 35 energizes the drive motor 25 again, and the discharge door 23 is lowered this time. Close the outlet 22.

On the other hand, for example, when the loading of the goods G to the spiral 15 falls in the middle, and the goods G do not fall even when the spiral 15 is rotated 180 °, the goods G open the outlet 22. The suspended plate 30 also does not operate because it does not pass.

Therefore, the bend end switch 33 also remains open, the fact that the bend end switch 33 is not detected by the detection in step S2, and from step S4 to step S5. In step S6, it is determined whether the flag which the control circuit 35 has as a function is set, and since it is reset here, the sales phrase 6 is opened in step S6 so that the contact point of the sales switch 28 is closed. If it is determined that the contact is not closed, the flag is set in step S7 to return to step S1, and the product discharging operation from step S1 to step S3 is resumed.

As a result, the spiral 15 is rotated 180 degrees again by the rotation of the sales motor 27, and the next product G is discharged.

In this case, if the product G is not discharged even by one time product discharge operation, the product discharge operation is repeated again. Therefore, it is possible to prevent the product from being sold due to the loading and unloading of the product G to the spiral 15. have.

Next, in step S4, it is determined whether the bend end switch 33 is closed based on the detection in step S2, and if the product G is discharged, the flow proceeds to step S8 as described above. If the bend end switch 33 is not closed even at this stage, the flow proceeds to step S5.

Here, since the flag is set, the process proceeds from step S5 to step S8 and the selling operation is finished.

In other words, when the product G is not discharged even by one product discharge operation, it is finished by repeating the one time discharge operation again.

Here, the merchandise outlet 28 is not discharged even in the first product discharging operation, when the bend end switch 33 is not closed in step S4, and the process proceeds to step S6 in step S5. When the output of the inverter 37 becomes "H" in this closed state, the flow proceeds to step S8, so that the product discharge operation is not resumed.

That is, a person who does the wrong thing opens the sales phrase (6), puts his hand into the merchandise sales outlet (5), and pushes the hanging plate (30) from the front. The product (G) falls by the rotation of the sales motor (27). Even if the suspended plate 30 does not operate, the control circuit 35 resumes the product discharge operation.

If this discharge operation is carried out as it is, two goods G are held on the goods lifter 17 behind the suspended plate 30, and the two goods G in the goods sales opening 5 are released. It is possible to drop the.

However, when the sales phrase 6 is opened to insert a hand, the sales phrase 6 abuts the sales switch 28, thereby closing the contact point of the sales switch 28, thereby making the step (as described above). From S6), the flow advances to step S8, and resumption of the product discharge operation is prohibited.

Therefore, the above-mentioned double sale does not occur and irregularities can be prevented beforehand.

In addition, although the hanging board 30 was comprised by the polycarbonate in the Example, it is not limited to this, It is light and it does not interfere as long as it can operate even if the goods G pass through the outlet 22 in any attitude | position.

According to the invention of claim 1, when the delivery of goods from the outlet is detected by the operation of the suspended plate, and the goods are stored in the goods storage column on the way, the goods do not fall and the goods are not sent out from the outlet to the goods outlet. Since the product discharge operation is resumed, it is possible to prevent the product from being sold due to product loading or failure.

In addition, according to the invention of claim 2, if the product sales detection means tries to deny the delivery of goods from the discharge port and opens the sales sentence, the sales sentence opening and closing detection means detects it and prohibits resumption of the product discharge operation. As a result, fraudulent duplication of sales can be prevented.
